Abstract: A method for performing channel scan within a multi-channel broadcasting program receiver includes: calculating a plurality of frequency representatives of intermediate frequency (IF) signals of one or more received multi-channel broadcasting program signals within a specific band of a plurality of bands; and locating a video IF signal out of the IF signals according to the frequency representatives in order to determine a frequency of a video carrier corresponding to the specific band, wherein the frequency of the video carrier is utilized as a reference for tuning to an associated channel. An associated multi-channel broadcasting program receiver includes a tuner, a processing module, a memory and a controller. The tuner is arranged to select one of a plurality of channels. In particular, the controller controls channel scan and further utilizes the frequency of the video carrier corresponding to the specific band as the reference for tuning to the associated channel.

Abstract: A television receiving system is disclosed, comprising an input terminal, a down-converter, an amplifier, an analog-to-digital converter (ADC), a demodulator, and an isolation circuit. The input terminal receives an RF signal. The down*converter, coupled to the input terminal, converts the RF signal to an intermediate frequency (IF) signal. The amplifier, coupled to the down-converter, amplifies the IF signal. The analog-to-digital converter, coupled to the amplifier, converts the amplified IF signal to digital data. The demodulator, coupled to the ADC, processes the digital data to generate baseband data. The isolation circuit, coupled between the amplifier and ADC, isolates the amplified IF signal from being affected by interference induced by the ADC.
